The SIG P220 was designed as a modern service pistol replacement for the P210, emphasizing simpler manufacturing and broader military and law enforcement adoption. It introduced the decocking lever rather than a manual safety and established the SIG-Sauer design language that carried through the P226, P228, and later generations. The .45 ACP variant was developed primarily for the US market.
